Brand Name: Global
Model Number: GBT
Place of Origin: Zhejiang, China (Mainland)
1.perfect performance with low melting point, good mobility and excellent conductivity
2.approved by Environment certificate
High Silver brazing alloys can provide perfect performance with low melting point,extensive flow properties and crate strong,ductile,rust-resistant joints condctivity, Suitable for joining all non-ferrous metals and ferrous metals except aluminum and magnesum.Flux is needed for brazing except for in protective atmosphere or vacuum brazing .Th addition of zinc/Tin can help as temperaturedepressant and reduce cost of filler metal.Nickel can improve the heat-resisting,rust-resisting and wetting properties of the alloy
